This invention relates to improvem n s in toilet seats and moreparticularly the hinge mounting thereof. y '8 The pr nc1palob'ect is toprovid a simple and ractical means in connection with the hinge mountingof the seat for friotionally r a ng checking the seat in its swingingmovement to and from lowered position so as to avoid the likeliho d ofits dropping and being cracked or possibly damaging the bowl, and for.frict onallv retaining the seat in its raised position to avo daccidental dropping and also to avoid humping the wall behind the bowl.1

According to my invention the pos s on the bowl on. which the] seatishingedly mounted provide abntments for sprin pressed frictionplungersmonnted in bo es provided therefor 'inthe back .of the seat, theposts having .rounc'led heads to provide tracksu faces' thereon forengagement by the plungers and being preferably conformed so .as tocrown portion ereof to retain the seat i raised position by theengagement of the plungers in the depressions, the restof the tracksurface "being conformed to impose 1ncreasing resistance to the movementof the seat sea approaches lowered position.

The invention is illustrated inthe accompanying drawing, wherein Figure1 is a fragmentary side view of a.

toilet bowl showing the hinge mounting of the seat in connection withwhich my invention is illustrated, the seat being broken away to showone of the spring-pressed plungers and its raised nosltion being 1nd1-cated in dotted lines;

Fig. 2 is a plan view of Fig. 1 on a somewhat reduced scale; and 1 Fig.3 is an enlarged elevational detail of one of the posts to illustratethe form of the track surface for the plunger on the head portionthereof. 8

The same reference numerals are applied to corresponding parts in thethree views.

The invention is shown applied to use 1n connection with a conventionaltype of toilet seat 4.- on a toilet bowl 5 of any suitable type. Theseat 4: has a pair of hinge arms 6 proj ecting rearwardly therefromhaving pivotal mounting on a pintle 7 received at its ends in sockets inthe heads 8 of posts 9. The heads 8 have neck portions 10, as shown, tohold the seat in the usual elevated relation 1provide a depression 011he to the rim of the o that toilet seats and bowls, particularly inPublic uildings, receive rather rough treatment and as a result of thebanging of the seat down onto he bowl or back agains t 'Waflthsre is aptto be damage do e to the bowl or to the wall and frequently the seat iscracked. According to t e present invention, I provide mean for iotjonal ly r training or chec i g the seat in its mo e-- ment to and f omlower d nositi nso hat it becomes impossible r a care ess indi dual tocause dam ge. I a so provide f r the retai ing of the seat definitely ina e tain raised position so that it wi l not be th o It is well knownagain the W211 norc'an it drop a ci enta ly n o ce rai ed.-

As illustrated, I provide a pair of plunger bores 11 in the seatentering from the rear side thereof in line with the heads 8 of theposts 9. Pluno'ers '12 received in these bores are extended under theaction of compression springs 13 into frictional engagement with track'surfaces 13 provided on the heads 8.

The ends of the plungers 12 1nay be suitably rounded, as shown, to avoidany likelihood of the seat catching when it is being raised .or lowered.The heads 8 ,are of rounded form, as shown; and the track surfaces '13are fiat but follow the contour of the head 8 for the most part,departing only to the extent indicated in Fig. 3 where the portionindicated in dotted lines at 14 represents the portion of the peripheryof the head removed or at least represents the variation in the contourof the head from a true round form, as in actual practice the head 8.may be molded from bakelite material and the form of the track 13 willbe determined in that way.

Thetrack surface has a depression 15 at the nolikelihood of bumping thewall and possibly marring it as well as the seat. It will also be notedby observation of Fig. 3 that the track surface commences with a givenradius near the crown portion of the head at the depression 15 and thatthe radius gradually increases toward the lower end of the track surfaceso that more and more resistance is imposed to the swinging movement ofthe seat as it approachesvlowered position. The reason for this will beobvious. It positively avoids any likelihood of the seat being bangeddown onto the bowl or of its dropping from raised position. It ispractically necessary to grasp the seat and move it from raised tolowered position as the seat will be held in any intermediate positiondue to the friction imposed by the plungers 12. V

I prefer to provide the plungers 12 of bakelite material impregnatedwith graphite as I have found in actual practice that plungers of suchmaterial will ride smoothly and noiselessly on the bakelite heads. Thereis also less wearing away of the track surface-0n the bakelite headswhen plungers of such material are used. However the principal purposein making this special provision is to eliminate the likelihood of asqueaking noise in the raising and lowering of the seat which mightotherwise result with the arrangement herein shown.

I claim:

1. The combination with a toilet seat having hinge arms projecting fromthe back thereof, and posts for hingedly mounting the same on a toiletbowl, of a plunger bore provided in said seat opening on the rearwardside thereof in line with one of the aforesaid posts, and aspring-pressed plunger received in said bore and extended therefrom intofrictional engagement with said post for yieldingly restraining the seatin its swinging movement to and from lowered position and for retainingthe same in raised position.

2. In the combination as set forth in claim 1, the provision of a posthaving a head portion providing a rounded surface to serve as a trackfor engagement by said plunger.

'3. In the combination as set forth in claim 1, the provision of a posthaving a head portion providing a. rounded surface to serveas a trackfor engagement by saidplunger, said track having a depression thereinonthe crown .of the head whereby to retain the seat in raised positionwhen the plunger rides into the depression.

4. In the combination as set forth in claim 1,-the provision of a posthaving a head portion providing a rounded surface to serve as a trackfor engagement by said plunger in swinging from raised to loweredposition and commencing with a portion of a given radius at the crownportion and increasing in radius from this point toward the lower end ofthe track whereby to impose greater resistance to the movement ofthe'seat as it approaches lowered position.

5. In the combination as set forth in claim 1, the provision of saidpost having a head portion of bakelite material providing a tracksurface for engagement by said plunger and the provision of said plungerof bakelite impregnated with graphite arranged to ride in frictionalengagement with said, track surface. 7

In witness of the foregoing I affix my signature. J. NIELSEN.
